The dopamine transporter (DAT) is a membrane protein belonging to the Neurotransmitter:Sodium Symporter (NSS) family, which also includes the closely related serotonin and norepinephrine transporters. NSS are responsible for clearance of released neurotransmitters (e.g. dopamine, by DAT) from the synaptic cleft. Function of NSS transporters in neuronal signaling implicate them in the mechanisms of action of abused psychostimulants, such as cocaine and amphetamine, and in various psychiatric and neurological disorders including drug addiction, schizophrenia, and Parkinson’s disease.
